Thank you for comment, Zuzana.
I checked permissions of all files. And I reached only “-quit” command for testing at last. Older version (1.0.3.6310) returned always zero at the termination by “-quit” command. I’ve changed error handler for 1.0.3.9696. However, code 4 is not normal, I think.
By the way, did you change anything related to update policy on December 1st? 1.0.3.6310 suddenly stopped processing at the beginning of reconstruction process due to an unknown error after December 1st 9:00 JST (it is 0:00 UTC). My scripts are running everyday 24H.
So I had to update 1.0.3.6310 to 1.0.3.9696 last Sunday. After changing my scripts for 1.0.3.9696, I met this issue.
